STUDY ON THE PROPERTIES OF CONCRETE UNDER THE INFLUENCE OF CEMENTING MATERIAL COMPOSITION
Based on the mechanism of shrinkage compensation,the properties of concrete under the influence of cementing material composition were investigated.On the basis of the preparation of raw materials,the preparation of main instruments and equipment,and the design of the test method of the strength and expansion performance of the compensated shrink concrete,the mix ratio of the compensated shrink concrete is designed,and the influence of different gel material composition conditions on the compressive strength and limited expansion rate of the compensated shrink concrete is explored.According to the response surface optimization method,the relationship between the influencing factors and the response value was established through the significance test.On this basis,it was proposed that the expansion coefficient was not caused by the expansion agent,and the expansion rate could be controlled by adjusting the composition of the cementing material.
